1969 Ford Cleveland heads

[goinbroke2]

HHmmm, lot of years since I even touched one, but;
2bbl 2.05 int 1.65 exh open chamber ALL (70 some cc I think)
4bbl 2.19 int 1.72 exh open chamber police int head 71-74
4bbl 2.19 int 1.72 exh close chamber adj valve train boss 351 1971 only
4bbl 2.19 int 1.72 exh close chamber hyd valvetrain 351 CJ 1971-74

Memory being what it is, I'm thinking the hyd 4bbl CJ head and PI head might be reversed.

And yes when your running a stockcar and they have a cyl pressure rule, one open chamber and one closed chamber head will give 155psi(165limit) and the open will give 120....until your caught 5 races later...don't ask LOL!
